Read more ↓Onix, the Rock Snake Pokémon, is a colossal creature first introduced in Generation I, hailing from the Kanto region. Its immense size and rock-hard body make it one of the most recognizable Ground/Rock-type Pokémon. Onix typically inhabits mountainous and cavernous regions, burrowing through solid rock with surprising speed and agility. Its diet consists primarily of the minerals and earth it consumes while digging, which further hardens its body over time, making it incredibly durable. Onix is known for its formidable presence in the early Pokémon games, particularly as Brock's signature Pokémon in the anime, where it showcased its unwavering defense and powerful attacks. Its evolution, Steelix, is achieved by trading Onix while it holds a Metal Coat, transforming it into a Steel/Ground type, further cementing its role as a sturdy, defensive Pokémon. Onix’s unique serpentine, rock-segmented form has made it a memorable and culturally significant Pokémon, representing strength and resilience within the franchise.
